I was carrying the stun baton in my characters hands. When i pushed the "x", in the inventory screen, to return the item to my back the item was duplicated and placed into free slots in my inventory (see other post).
Subsequently I was not able to move the item from the slots it was designated to in my inventory nor was I able to drag and drop it from my back. The item was frozen in place both on my back and in the inventory.
Upon relog into the game the stun baton was unfrozen and I was able to drop the duplicated item and drag and drop the baton on my back.
